You can use ssh-keygen for this. Despite its name it can do many more things than generating keys: dennis@lightning:~$ ssh-keygen -l -f .ssh/id_rsa.pub 2048 68:df:b2:22:d8:43:5d:36:75:c1:d8:59:c0:8c:22:e8 Dennis Kaarsemaker (RSA) dennis@lightning:~$ ssh-keygen -l -f foo.txt foo.txt is not a public key file.
RSA is generally preferred (now that the patent issue is over with) because it can go up to 4096 bits, where DSA has to be exactly 1024 bits (in the opinion of ssh-keygen). 2048 bits is ssh-keygen‘s default length for RSA keys, and I don’t see any particular reason to use shorter ones. (The minimum … Read more
Check the contents of key_name, if the agent says invalid format, then there’s something wrong with the key – like .. are you sure that’s the correct key? Even if it’s not the private key you need, the ssh agent won’t return invalid format if the key is working, you simply won’t be able to … Read more
I would prefer the ssh-keygen -y -e -f <private key> way instead of the accepted answer of How do you test a public/private DSA keypair? on Stack Overflow. ssh-keygen -y -e -f <private key> takes a private key and prints the corresponding public key which can be directly compared to your available public keys. (Hint: … Read more
I’ve created an RSA keypair that I used for SSH, and it includes my email address. (At the end of the public key.) That part of an ssh key is just a comment. You can change it to anything you want at any time. It doesn’t even need to be the same on different servers. … Read more
For Git Bash If you are running msysgit (I am assuming you are) and are looking to run Git Bash (I recommend it over TortoiseGit, but I lean to the CLI more than GUI now), you need to figure out what your home directory is for Git Bash by starting it then type pwd (On … Read more
You can’t just change the delimiters from —- BEGIN SSH2 PUBLIC KEY —- to —–BEGIN RSA PUBLIC KEY—– and expect that it will be sufficient to convert from one format to another (which is what you’ve done in your example). This article has a good explanation about both formats. What you get in an RSA … Read more
In order to make it work you need to convert key from str to tuple before decryption(ast.literal_eval function). Here is fixed code:
Your code has undefined behaviour because you are trying to assign l from an uninitialised array str. I’m guessing you got your functions confused and meant to write the opposite That code assigns l to str. Use the following code to work out how big str needs to be
I have a pair of keys to epadmin on machine A. I copied them on machine B in home folder of epadmin via scp in folder .ssh command for access : ssh [email protected] Here is a piece of -vvv(Verbose) log I can’t login without password Piece of sshd_config. I have tried to uncomment RSAAut and … Read more
